Hello. I am new here...I upgraded to an 04 Ram Quad Cab 4.7l about a year and a half ago from a Nissan Frontier. I love this truck. I want to start pulling a travel trailer. My truck did not come with the factory tow package but I have added the hitch and the mopar 7 pin harness...no problem. I need to install the electric brake and was wondering if there was a harness already under the dash. I have looked but can't seem to locate one. Will I need to hard wire this? Thanks.
